YARN SPINNING OR TWISTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 660,628, dated October 30, 1900.

Application filed May 11, 1900. Serial No. 16,291. (No model.)

To all whom it 71b0 concern.-

Be it known that I, GEORGE O. DRAPER, a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Yarn Spinning or Twisting Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

This invention has for its object the production of novel apparatus pertaining to yarn spinning or twisting, and more particularly such as relates to the so-called rotary-ring type, wherein the traveler is supported by and travels upon a rotatable ring, thus permitting very high spindle speed.

The construction forming the subject-matter of my present application has various novel and peculiar features, which will be hereinafter described, and particularly pointed out in the following claims.

Figure lvis a top or plan view of an apparatus embodying one form of my invention. Fig. 2 is an enlarged vertical section thereof on the line 00 m, Fig. 1, the parts being shown at rest. Fig. 3 is a similar View, but with the movable members in the position assumed when the frame is running at high speed; and Fig. 4 is a vertical sectional detail of a modification to be described.

The apparatus herein shown is designed to take the place of the usual ring now in general use on spinning or twisting frames, and as the other parts of the frame form no part of my invention and may be of any approved form I have herein shown only a portion of the ring-rail 5, Figs. 2, 3, and 4. Upon the rail I mount a metallic holder 6, circular in form and surrounding the spindle-opening in the rail, said holder being provided with radial notches 7 for headed attaching-screws 8. An ann ulargroove 9 is made in the upper surface of the holder to receive the foot of an upright annular guide or separator 12, having alaterally flanged or enlarged head 13. The guide is held stationary by frictional engagement with the holder, and before the said parts are assembled the guide is interposed between two loose rotatable rings-l5 16, which are free to move radially to a limited extent under the stress of the yarn. and they are also axially movable, the head 13 of the guide preventing undue upward movement. A traveler 30, of usual bowed form, having inturned ends 31 32, is brought into operative engagement with the loose rings, as in Fig. 2, straddling the guide, at such time the other sides of the rings 15 16 resting on the holder 6. When the frameis started, the I raveler moves around the rings, giving them a'species of gyratory movement, until as the speed increases the rings lift bodily and remain suspended, rotating in unison with the traveler, in the position shown in Fig. 3. The radial movement permitted the rings enables them to center themselves, and the guide retains them in place and prevents undue movement. By the rotation of the rings with the traveler the friction on thetraveler is decreased and higher speed of spindle rotation can be employed.

In Fig. 4 the holder 6 supports a fixed guide 18, having the under faces of its T-head 19 flattened, and the rotatable rings 27 28 are shown as cylindrical webs having oppositelyturned flanges 270 280, respectively, at their upper ends, to be engaged by the traveler 30. The operation is substantially such as hereinbefore described, except that the gyratory movement of the rotatable rings is not observable.

The construction shown in Figs. 1 to 3 is simpler and'cheaper, the rings 15 16 being shown as substantially circular in cross-section.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a spinning or twisting frame, a plurality of rotatable rings, and a traveler in operative engagement therewith.

2. In a spinning or twisting frame, a plurality of rotatable rings, a traveler in operative engagement therewith, and fixed means to limit the movement of the rings.

3. In a spinning or twisting frame, inner and outer rotatable rings, an annular, fixed guide interposed between the rings, and a traveler in operative engagement with said rings.

4. Ina spinning or twisting frame, two conwith the rings and spanning the upper end of the guide.

7. In a spinning or twisting frame, two rotatable rings substantially circular in crosssectiomand capable of gyratory movement, a traveler in operative engagement with the rings, and means to guide the latter.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE O. DRAPER.
